Large video files (over 2.14gb) fail with error "Unsupported media type" #56
Description
I've been running some video tests and hitting the same 'unsupported media type' error for a variety of files - and eventually concluded:
- the media type (QuickTime/MPEG4) is supported, other than ProRes
- file sizes larger than somewhere between 2.14 GB and 2.43 GB fail with the same error message
The traceback is below the table.
